NEW YORK ASSIGNOR TO H- S HOHNER, OF

ACCORDION.

Specification of Letters Patent.

Patented Oct, 29, 1907.

Application tiled March 11, 1907- Serial No. 361.634:-

To all whom it may concern:

Be it known that l, EDwlinD E. llnitnxnhn, a citizen ot' the linited vStates, residing at New York city, \lanl art-an, county and 5 ate of New York, haye invented new and usetul l mproyemeuts in Accordions, of which the iollowiug a specification.

'lhis inyentiou relates to an improved accordion, and more particularly to a noyel construction oi the treble keyboard, by means oi which a chronndic scale is obtained and at the same time the ordincry arra-ngeinentoi' the key to which accordion players are accustomed, is retained.

The accompanying drawing represents a plan of part of an accordion embodying my invention.

'l'he treble 'key-l, oard 10 is provided with an outer row of keys li 1. which correspond to the keys as generally used in accordions and to which the play That is to st each key actuates two reeds, one note being produced by contracting the bellows, while a second note is produced by expanding the bellows. The reeds are so toned, that by alternately contracting and expanding the bellows the (janajor scale is obtained, excepting that tor consecutiye notes A and 13, the bellows must be expanded. "his arrangement is rendered necessary on account of the odd number of the notes in the scale, so that the tonic note is always sounded by cornpressing the bellows, and that chords will always be produced when the bellows are compressed or expanded, irrespective which particular keys are depressed. The notes (I, E, U, termed by compressing the bellows are marked in the drawin on top or their respectiye keys, while the notes D, h, A, B, formed by expanding the bellows are marked at the bottom of such keys,

itbeing observed that the notes A, as well as B, are

marked at the bottom. In addition to the outer row 0i keys ll-2l, the key-board is provided with an in ner row of keys 3l.-- lt), the latter being 4 ranged to intercalate with the keys of the outer row. Each of the keys 3t- .tt) also sounds two d ierent notes, one by contraction and the other by expansion of thebellows.

Tire tuning is such that the note produced by any one inner key on compression oil the bellows is a semitone higher than the note oi the preceding outer key prod need on such compression. in like manner, a

note produced by any one inner key on expansion oi notes Slit, Dfi, key 34 forms in similar manner the notes i hi keyiio the notes Gi Ag, of a C scale. ltwill be observed that in carrying out this arrangement, the tonic notes i, and the snbalomiuant notes it, are duplicated, they being .t'ormed upon the outer as well as upon the inner rows of keys, the note t, on any one inner key being the sharp of .13, on the preceding outer key. So also, the note i, on any one inner key is the sharp of ii, on the preceding outer key.

With the example illustrated, a proper manipulation of the outer row ot keys will produce a dialonic (l major scale as already dc. ribed. it the keys ot the inner row are manipulated in like manner, a diatonic major scale is produced, it being thus seen that the diatonic scale produced by the inner row of keys pitched a semitone higher than that produced by the outer row. By proper manipulation oi the outer row is meant that the bellows are tirst contracted and then expanded tor each of the keys 13, 14 and 15, to successiyely sound the notes C, D, l5, 1?, G, A. For producing the seventh and eight notes it, by key 16, the bellows must first be expanded and then contracted tor the reason previously stated. In like manner, the diatonic oh major scale is produced by the inner row of keys 33, 34, 35 and 36, the bellows being first contracted and then expanded tor keys 33 34 and 35, to sound the notes Gill, ([Ul' dealt. For key 36, the bellows are tirst expanded and then contracted to successively sound the seventh and eighth B11 notes (G),

By the coustructitnt described, a chromatic scale is obtained with all the advantages [lowing therefrom. At the same time the keys 111- i. of the outer row are not in any way changed from those which are generally iound on accordions. in this way the instrument may be used equally well by a player accustmned to the old style only, and by one who is sutliciently skilled to avail himselt of the chromatic arrangement.

I claim:

1. An accordion haying a first and a second row of keys. and a pair of dit'terently toned sound {)t'OtltltiGlS actuated by each of said key s, the sound producers of any one key in the second row being pi (shed a setnitoue hie-her than the sound producers ot' the preceding key in the first row, substantially as specified 2. 1111 accordion haying a first and second row 01. keys, and a pair of differently tuned sound producers actuated by each of said keys, tonr successiye keys of the first row actuating the sound producers ot the notes C, I); E, L: G, A; (I, and tour successive keys of the second row actuating the sound producers ot the notes 0;, 1):; F, F11:

t). substantially as specified. ed by me at New York city, this 7th day of March, 1907.
